It is probably just a shell. They call it a "potential flyer". The damn thing is up on blocks like it was parked in the wrong part of town and got stripped. I don't think you can go to you local auto parts store(or anywhere for that matter) and pick up the parts you would need to complete this "project".
I remember all the problems the Brady kids had when they found that tiki god on the construction site. Bad Hawaiian mojo is nothing to scoff at.
On a more serious note, you would think that they could use special effects for something like that.
